    training resources for new/inexperienced techs?

    ive taken on a job of replacing all the refrigeration equipment at a very large commercial facility. the business has a maintenance staff that the owners have given me to use for this job. the staff is made up of a wide range of experience, but none includes refrigeration. as such they will have very little to nothing to do with the sealed system, but i would like for them to at least understand defrost termination and defrost timers. i fear i dont make a very good teacher and would very much prefer an online source to at least explain the basics. any help in locating this would be appreciated.

    i did just that (using a commercial alarm bell instead of a light bulb) for teaching time initiated defrost but its a little more difficult with defrost termination. instead of banging my head in frustration i would rather just say "go read this to get the basics and then we will discuss it".
    thanks,

    exactly! i know how it works but trying to explain it to someone that has never heard it before (at least on a level where they can understand it) is somewhat difficult for me. finding a source to explain it would make things so much easier.

    Take a piece of plywood. Mount an 8145-00, two Acme 700 fan motor kits, a bohn three wire dt/fd, a light bulb.
    Wire it in away that the light bulb indicates defrost and one fan motor indicates refrigeration. Position Bohn dt/fd so the heat from the bulb will terminate the defrost, the second fan kit cools the fan delay until it makes contact and starts the motor used to simulate refrigeration.
